问题补充：

enough money, Li Hua was unable to buy the new house.

A. Not saved

B. Not having saved

C. Not to save

D. Not saving

答案：

A. Not saved

(答案→)B. Not having saved

C. Not to save

D. Not saving

解析：选B考查非谓语动词。句意：由于没有攒下足够的钱，李华买不起这套新房子。save这个动作发生在buy之前，且save与Li Hua之间是逻辑上的主动关系，故用现在分词的完成式。再结合句意可知，应用分词的否定形式，故B项正确。
